Procella's Yoru Nagatsuki and You Hazuki are childhood friends whose families have known each other for generations. Their personalities, preferences, strengths, and weaknesses are opposites, leading them to sometimes drift apart. However, as they continue to work under Procella, the two of them are true partners. They've spent most of their lives together. They can tell each other things too difficult to say to others. And because of that relationship, they sometimes clash... This is the, in a sense, same old story of an argument they have during a dance lesson while preparing for the Full Moon Festival.
When you work as a duo, 
you're often compared to each other.
عندما تعمل مع شخص كثنائي، فغالباً
ما تُقارنَان ببعضكما الآخر
Wenn man zusammenarbeitet,
vergleicht man sich unweigerlich.
Se suele comparar mucho a las duplas
En los dúos es inevitable comparar
On n’échappe pas à la comparaison,
surtout en paire.
Quando si lavora in coppia,
si viene spesso paragonati l'uno all'altro.
Quando se trabalha em dupla,
é normal que comparem um com o outro.
Когда работаете в паре, вас неизбежно
сравнивают друг с другом.
